Kendall Jenner took to Instagram yesterday (Sept. 22) to debut what looks to be some lighter locks.


The 17-year-old reality star and model appears to have dyed her hair a light brown, ditching her darker 'do for some highlights.



She also shared pics from her weekend at the iHeart Radio Music Festival with her sisters Kourtney and Khloe Kardashian and Kylie Jenner.



And although Kim K was absent from the festivities, it looks like Kendall followed in her newly-blond big sister's footsteps.
